Floribunda rose plant named ‘Bagstream’

ABSTRACT

A new and distinct variety of Floribunda rose plant is provided which forms in abundance on a substantially continuous basis attractive double bright orange blended with yellow blossoms. The vegetation is vigorous and the growth habit is compact and bushy. Attractive ornamental semi-glossy dark green foliage is formed. Good disease resistance to blackspot is exhibited. The new variety is well suited for growing as distinctive ornamentation in smaller gardens and along walkways. The new plant is particularly well suited for growing in West Coast, U.S.A., climates.

Botanical/commercial classification: Rosa hybrida/Floribunda Rose Plant.

Varietal denomination: cv. Bagstream.

SUMMARY OF THE INVENTION

The new variety of Floribunda rose plant of the present invention was created by artificial pollination carried out during August 2001 at Fallbrook, Calif., U.S.A., wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the ‘Jacsur’ variety (U.S. Plant Pat. No. 9,494). The male parent (i.e., the pollen parent) of the new variety was the ‘Jacyimp’ variety (U.S. Plant Pat. No. 11,882). The parentage of the present invention can be summarized as follows: ‘Jacsur’×‘Jacyimp’.

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Floribunda rose plant of the present invention possesses the following combination of characteristics:

-   -   (a) abundantly and substantially continuously forms attractive         double bright orange blended with yellow blossoms,     -   (b) exhibits a compact and bushy growth habit,     -   (c) forms vigorous vegetation,     -   (d) forms attractive ornamental dark green foliage with a         semi-glossy finish, and     -   (e) exhibits good resistance to blackspot.

A new rose variety is provided having attractive bright orange blended with yellow blooms, combined with substantially continuous blooming and resistance to blackspot. The new variety is particularly well suited for growing in West Coast, U.S.A., climates.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as attractive ornamentation in parks, gardens, public areas, and residential landscapes. Accordingly, it is particularly well suited for growing in the landscape. The new variety fits well for growing in smaller gardens and along walkways. The bloom coloration contrasts nicely with the semi-glossy dark green foliage.

The characteristics of the new variety have been found to be homogeneous and stable and are strictly transmissible by asexual propagation at Wasco, Calif., U.S.A., such as budding, grafting, and propagation by the use of cuttings from one generation to another. Accordingly, the new variety can be asexually reproduced in a true-to-type manner.

The new variety has been named ‘Bagstream’, and will be marketed under the TANGERINE STREAMS trademark.

The new variety can be readily distinguished from its ancestors upon an inspection of the blossoms. More specifically, the ‘Jacsur’ variety forms primarily light orange blossoms having a lesser number of petals. The ‘Jacyimp’ variety forms yellow-orange blossoms also having a lesser number of petals. When the new variety is compared to the ‘Gingersnap’ variety (U.S. Plant Pat. No. 4,330), it is found that the ‘Gingersnap’ variety forms larger orange blossoms which also display a lesser number of petals.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in a color illustration of this character, typical blossoms of the new variety. The illustrated plant was approximately two years of age and was being grown outdoors on its own roots during June at West Grove, Pa., U.S.A.

DETAILED DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two-year-old specimens of the new variety during June while grown outdoors on their own roots at West Grove, Pa., U.S.A.
